Glad to hear it! I created it from scratch, HOWEVER, it is leveraging existing software packet radio modems, TNC software. There are many out there for packet radio. You connect to it via a direct TCP connection, and send the data. The receiving side does the rest. I created the systems for connecting, handshaking, the back and forth, splitting of packets based on size, CRC data checksums, and more. Leveraging a few python libraries for sure. I could have saved a HUGE amount of time if I was able to utilize a packet modem software in python that did what I wanted. Unfortunately I couldn't find a good one.
